A shallow water equations-based model with an improved local time-stepping (LTS) scheme is developed for modeling coastal hydrodynamics across multiple scales. from large areas to detailed local regions. To enhance the stability of the shallow water model for long-duration simulations and at larger LTS gradings. a prediction-correction method using a single-layer interface that couple... https://parisnaturalfoodes.shop/product-category/herbatint-6n/
